. i i V l I I SPECIFICATION forming part of Letters Patent No. 312,784,dated February 24, 1885 Application filed August 2 To all whom it mayconcern:

Beit known that I, JOHN B. WVOOD, a citizen of the United States,residing at Brooklyn, in the county of Kings and State otNew York, haveinvented a new and useful Composition of Matter to be used for Paint, ofwhich the following is a full, clear, and exact specification.

My composition consists of the following in- IC gredients, combined inthe proportions stated, viz: creosgte or dead-oil, eight gallons; opal:tar six gallons; spirits of turpeigtine', one gallon; plumbago, eightounces, by weight. These ingredlentsare to be thoroughly mingled by I 5stirring or otherwise. 4

- In the abovenamed composition is produced a paint useful forapplication to the bottoms of marine and other vessels, whether made ofwood or .iron, to smoke-stacks, and iron- 20 work exposed to air andwater and liable o rust, and to outside brick, gables, and t e rearTl'f'ho'uses, possessing numerous advantages over the common kinds ofpaint now employed for such purposes. It is a black liquid com- 25position, which is always read-y for use, and is applied'by a brush,under which it flows freely.

For protecting the bottoms of wooden vessels it is found to be muchsuperior to the ordinary copper paint which is now extensively appliedto them, for, instead of covering the outside of the wood like aplaster, as copper and many other paints do, it penetrates and fills itspores, and, being itself absolutely water-proof, thereby renders thewood better adapted than such other paints can to withstand the actionof the water. \Vhen this composition is applied to the bare wood,sea-worms will not enter the wood and barnacles will not grow upon it.-\Vhen used upon iron vessels (and it makes a good covering for theinside as well as for the outside) orsmoke-stacks, or iron-work of anydescription which it is desired to protect from exposure to the air or5,1884.

water, it excels all other of the common compounds or paints adapted tosuch uses. It will not flake or scale off, and th e'iron will not rustunder it. It is anti-fouling on the bottoms of iron as well as oi woodvE'siels, and prevents .barnacles or grass from growing thereon.W'hether it be applied to wood or iron vessels, two or three coats isthe proper.

quantity to use. For outside brick, gables, and the rear of houses it isuseful to prevent rain from entering the bricks, and it keeps the wallsentirely free from dampness. It is much cheaper than other compositionsof its class, which is dueto two causes-the quantity in earh cise beingthe same: first, it costs less to i i 6o make it than to make any of theother kinds, and, secondly, it covers a greater surface than any of themcover.

\Vhile the proportions above given are Suh g as in y porinients havebeen found to Prof duce the best results, still these proportions may besomewhat varied without materially altering the character of thecompound.
